RustedSciThe 0.4.16

//! Checked-in generated Rust fixtures for `CodegenIR` tests.
//!
//! These functions intentionally look like emitted `RustEmitter` output.
//! They let us verify an important intermediate milestone:
//! `Expr -> emitted Rust source -> compiled Rust function -> numerical result`.
//!
//! This module is test-only for now. Later, the same pattern can be upgraded
//! into real file-based code generation for large residual and Jacobian blocks.
